56k Ohm 0.25W Carbon Film Resistor - 5% Tolerance (Pack of 5)

Product Description The 56k Ohm 1/4 Watt Resistor is a reliable high-impedance passive component designed for signal conditioning, timing, and biasing applications. These resistors feature a 5% tolerance, ensuring consistent performance for standard pull-up/pull-down networks and RC filters. With a standard 0.25W power rating, they provide stable resistance in a compact axial package, making them ideal for high-impedance analog sensor circuits and digital logic stabilization.
